Sludge Dewatering

Dewatering is a physical unit operation used to separate the solid matter and water in sludge, resulting in a high solid content stream “cake” and a liquid stream. For effective solid liquid separation, chemical conditioning is required.

Dewatered sludge and biosolids are generally easier to handle than thickened or liquid sludge. In most cases, dewatered sludge may be shoveled, moved about with tractors and transported by belt conveyors. Dewatering is required normally prior to incineration of the sludge, composting, thermal drying and landfilling sludge and biosolids in monofills.

In mechanical dewatering devices, mechanically assisted physical means are used to dewater sludge more quickly. Other dewatering devices rely on the application of electric and heat energy.
